Ephesians 5:13

13 but everything exposed by the light becomes visible,

Ephesians 5:13 In-Context

11 Take no part in the unfruitful works of darkness, but instead expose them.
12 For it is shameful even to mention what such people do secretly;
13 but everything exposed by the light becomes visible,
14 for everything that becomes visible is light. Therefore it says, "Sleeper, awake! Rise from the dead, and Christ will shine on you."
15 Be careful then how you live, not as unwise people but as wise,
